Suzuki DT90 1996. Stops in 15 seconds..

[Fjordlann]

New in this forum, from Norway so there will be some typing errors!

I have a 1996 Suzuki DT90.

It starts fine, idles good. But after 15 seconds it stops. It will start instantly after shutdown.

The alarm sounds every 5 second, and sounds for just about a second.

The TPS is new, ignition timing resistor is new, carbs rebuilt, fuelpump rebuilt,
water pump impeller is new. good compression.

If i disconnect the TPS it will run for hours, but as soon I connect the TPS it stops. Thats why I bought a new. But that didnt change anything.
When it runs with TPS disconnected the alarm still sounds as mentioned.



Do anyone have an idea? Is there anything I should check?

Without the diagnostic to see what fault code is being set the only thing can do is to test all sensors to see if within specs.

No diagnostic..
just the sound alarm.

The oil inj. tank is removed, is there anything that I need to disconnect\jump wires or something to make it work without the oil injection system?

Check every system sensor you see.

Lifting this post ...

The Rev and OIL light is on on. beeper sounds every 5 seconds.

If i jump the oilflow sensor the REV light shut off. But OIL and buzzer still on.

Any ideas?
